* | Q*Application: don't allocate memory just to compare C stringsMarc Mutz2016-01-233-37/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of creating a QByteArray, possibly normalizing a leading '--' (one allocation, plus possibly one copy), simply use the old 'ol str(n)cmp, skipping the first character if the argument starts with '--'. It also fixes parsing of -stylesheet and other options which were erroneously parsed using indexOf() != -1, when they should have used startsWith(). Also saves 504/742/522b in text size for QtCore/QtGui/QtWidgets, resp., on optimized GCC 5.3 Linux AMD64 builds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | -developer-build enables -Werror=undef, which uncovered a bug inside qcompilerdetection.h. According to the Dinkum headers, it is necessary to account for three different states concerning the values of the _HAS_* macros: 1. undefined 2. 0 3. 1 Therefore, it is necessary to check both whether it is defined and if it is not 0. Only checking whether a given macro is 0 will generate a trap by -Werror=undef. (__GLIBCXX__ is the sole exception).

Instead, make them take references and move them to the private section of QTextCursor.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building QNX on MS-Windows, make magically adds the Msys root as prefix to variables whose values look like paths; this applies to both environment variables and variables given values on the command-line. When we don't actually want to install under the Msys root, this is unwelcome "help". So (for MinGW's make) support a magic prefix of our own, @msyshack@, that'll make a path value for INSTALL_ROOT not look like a path to make; we can then strip it off when we come to use it.

| | | | | | | | | | | | | | | | | | | | | | | | Commit 6e6f27b6 made it possible to set the PKG_CONFIG variable using CROSS_COMPILE as a prefix. The problem with that solution is that it makes pkgConfigExecutable() skip the environment setup for pkg-config as well, as it expects the pre-set command to be self-contained - which it isn't. To avoid this problem we need to store the pkg-config define in the device spec in a separate variable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The native socket engine used strcpy for WinRT, which tries to copy terminating null character. The QSocketNotifier::async_readDatagramSlot autotest uses a buffer of size 1, which causes readDatagram to overwrite the buffer on the stack. Hence use memcpy instead to protect from additional copies beyond barriers. Note that we cannot use qstrcpy as that does a buf[size-1] = '\0' at the end, which would remove content for a buf size of 1.

In noDeclarativeParentChangedOnDestruction(), the declarativeData pointer is, however, set to a local QAbstractDeclarativeData instance, which, being an empty class, has size 1 and alignment 1. Depending on the compiler's idea of bit field order, this code either read uninitialized data from the dummy object, or else some random stack memory outside any (valid) object. What caught UBSan's attention, though, was the difference in alignment between the two classes: src/corelib/kernel/qobject.cpp:917:9: runtime error: member access within misaligned address 0x7fffc9cf706f for type 'struct QAbstractDeclarativeDataImpl', which requires 4 byte alignment Fix by providing a properly initialized object of the correct type.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While a native dialog is open, the application message queue is handled by the native event loop which is external to Qt. In this case, QEventDispatcherWin32::processEvents() does not run and socket notifiers will not be activated. So, this patch moves the notifier activation code into the window procedure, which enables socket event processing with native dialogs.

QWidget::mapFromGlobal() does not work correctly when the widget is a child widget of another widget embedded into a QGraphicsView with a transformation (scaling/rotation). It starts applying offsets going up the widget tree (just as mapToGlobal) until it hits the embedded widget not taking into account the transformation. It would need to go in from to top to bottom or better be reimplemented such that a QTransform for mapping coordinates from/to global is determined which is then applied in reverse.
